Had a great stay at Ken's place.
Ken was very easy to reach, and resolved any questions we had quickly and efficiently.
The condo is in a high rise that is mostly occupied by a business hotel. Room was clean and well-equipped, fit for a Japanese business traveler. All facilities are modern and work well. I particularly liked the AC, and the bathroom. Very nice shower, shower pressure, hot water. Large TV, good fridge etc. Had no problems with noise or insects.
Small drawbacks: Pool maintenance a bit slack compared to other high rise buildings I've seen, but that is probably not much the host can do about. Immediate area is not too nice, but the location is very close to the MRT, so you can quickly go anywhere you like.
